HENRY WILKINSON, OF OLDHAM, ENGLAND.

MACHINE FOR OPENING AND CLEANING COTTON AND OTHER FIBRO-US MATERIALS.

Application filed May 23, 1923. Serial 1T0. 640,877.

To all whom it may concern:

Be it known that I, HENRY WILKINSON, a subject of the King of Great Britain and Ireland, residing at 500 Highfield Terrace, Barrowshaw, Oldham, in the county of Lancaster, England, have invented new and useful Improvements in Machines for Opening and Cleaning Cotton and Other Fibrous Materials, of which the following is a specification.

The invention relates to machines used for opening and cleaning cotton and other fibrous materials, and particularly to machines known as the exhaust opener lap machine, down stroke cylinder opener and lap machine, and scutchers, all of which have a down stroke cylinder, or down stroke bladed beater, or both, to which are connected dust cages and exhaust fan, and which usually have a lap forming arrangement, although I do not confine myself to the lap forming arrangement as the sheet of cotton from the cages may be delivered loosely either on the floor or to another machine, neither do I confine myself to the number of cylinders or heaters, or to the diameter of same, in any one machine.

In this invention, as an essential novel feature, I make the trunk delivering fibre from the cylinder or beater to the cages, of the full width of the machine, and use in combination with such a trunk, a beater or cylinder in which the grid bars are arranged around about three quarters of the circumference of the heater or cylinder which provides the outlet for the fibre on the same side as the feed, as shown in Letters Patent of the United States No. 1,452,133, issued to me under date of April 17, 1923.

The trunkto receive the fibre from the cylinder or bladed beater is curved and connected to a trunk or return bend to carry forward the fibre to the cages.

By having the trunks the full width of the machine an important advantage arises as the cotton is delivered by the trunks to the cages or other receiver in an even level sheet.

In the accompanying drawings,

Fig. 1 shows in sectional side elevation the invention applied to an exhaust opener.

Fig. 2 is a cross section of Fig. l on the line A-B.

Fig. 3 is a cross section taken through the line 0-D, and in Fig. 4 the invention is shown applied to a scutcher.

In the exhaust opener shown in Fig. 1 the beater a co-operates with grid bars I), bwhich are carried round from the feed rollers 0 about three quarters of the circum ference in which the beater a rotates. This provides an outlet (Z for the fibre at the same side as the feed, and the grid bars b are disposed at an opposite angle to the other grid bars 6, as disclosed in my prior U. S. Patent No. 1,452,133 applied to a porcupine cylinder. The fibre from the outlet d is induced into a curved trunk e, which, in this invention, is the full width of the machine as shown more clearly in Fig. 2. The curved trunk e is connected to a trunk 7 also the full width of the machine, as shown in Fig. 3, and this trunk is or may be provided with hinged doors 9, h to provide access to the trunk f for cleaning purposes. An air opening 21 admits air to the grid bars. The cages j j receive the fibre from the trunk f in an even level sheet, which is fed forward or removed from the cages in any convenient manner. The fan for inducing the necessary air suction through the cages and trunks d, e, f, is shown at k.

In Fig. 4 the invention is shown similarly applied to a scutcher, like parts bearing corresponding letters of reference. The curved trunk e and trunk f are also, it must be understood, made the full width of the machine as shown in Figs. 2 and 3. These feed trunks e, f formed the full width of the machine, to receive the fibre as it leaves the beater or cylinder and to feed it forward through the machine, form the essential novel feature of the invention and also the com bination of such feed trunks with a cylinder or bladed beater with grid bars arranged for about three quarters'of the circumference and having a delivery opening for the fibre at the same side as the feed.

I declare that what I claim is:

In a machine of the class described the combination with cylinders or beaters provided with grid bars arranged for about three quarters of the circumference and in which a portion of the grid bars are arranged at an opposite angle to the other portion and havlng a delivery outlet at the same side as the feed, of a trunk or trunks Elie full width of the machine to deliver the In testimony whereof I have signed my name to this specification.

HENRY WILKINSON.
